Huangtian Old God

In ancient times, the Haotian God and the Huangtian Old God competed for the dominance of heaven. God Haotian won, sealing the old God Huangtian and his followers under the Nine Earths, and erasing all memories of them in the world. However, the old gods have not died. They use dreams and whispers to find the "door" that can break the seal. Zhang Jiao, a compassionate doctor, accidentally became the vessel chosen by the old gods while on the way to treat a plague.
